On page 12 we learn that UTM is a form of TM. However there is no way one can construct their relationship just from reading what is written there. Trial and error reveals $ cat e ll='121 24' echo $ll|proj +proj=utm +lon_0=123 echo $ll|proj +proj=tmerc +lon_0=123 +x_0=500000 +k=0.9996 $ sh e 296550.01 2655671.20 296550.01 2655671.20 Indeed the above would be a great example to put in the document. Also revealed is the completely unmentioned +k=0.9996 .
